In this issue, the editor will bring you about how to use the dedent function in python to delete the leading spaces in the string. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

In python, you can use the dedent function of the textwrap module to delete leading spaces in a string, which solves the conflict between indentation of python code and writing multiline strings, and avoids defining multiline strings globally.

If 3 > 2:

Text = ""

Delete leading space

It really works.

"

Print (text)

In this code, a string is defined in triple quotes in the if clause. There are multiple lines in the string, and the result of the program execution is

Delete leading space

It really works.

When a string is defined, there is a space in front of each line, so when it is output, there will also be a space, so how to eliminate the space in front of each line? when defining a string, is it OK for each line to write close to the beginning? just try.

If 3 > 2:

Text = ""

Delete leading space

It really works.

"

Print (text)

This time the actual output met our expectations, with no spaces in front of each line of string, but writing the code in this way messed up the indentation level and, while grammatical, undermined the beauty of python. One possible solution is to define such strings in the global scope, so that there is no problem of breaking indentation, but the definition of such strings still affects the reading experience of the code, and the best way is to use the dedent function of the textwrap module.

From textwrap import dedent

If 3 > 2:

Text = ""

Delete leading space

It really works.

"

Print (dedent (text))

Output result

Delete leading space

It really works.

Using dedent, it removes the leading space of each line of string, maintains the indentation of python code, and avoids defining too many such strings in the global scope.

The above is how to use the dedent function to delete the leading spaces in the string in the python shared by the editor.
